Calamus moti is a climbing rainforest plant in the palm family Arecaceae, which is endemic to Queensland. It has a slim flexible stem which does not support the plant, instead it climbs to the forest canopy with the assistance of long tendrils armed with stout recurved hooks.

Description

This is a clustering, climbing palm with stems up to Шаблон:Cvt in diameter and Шаблон:Cvt in length, making it the largest of the eight Calamus species found in Australia.Шаблон:R The leaves are up to Шаблон:Cvt long and are pinnate with 35 to 50 leaflets either side of the rachis. The underside of the rachis has three longitudinal rows of stout recurved hooks.Шаблон:R The leaflets are linear-lanceolate, up to Шаблон:Cvt long by Шаблон:Cvt wide, with very fine barbs on their marginsШаблон:R On the upper surface of each leaflet there are two longitudinal rows, one either side of the central vein, of spines measuring up to Шаблон:Cvt long.

The leaf sheaths completely surround the stem and are armed with stout yellow-green spines about Шаблон:Cvt long arranged in oblique combs. Flagella armed with stout recurved barbs are produced from the leaf sheath and act as grappling hooks providing support for the flexible stem.Шаблон:R

On older sections of the stem the fronds and their leaf sheaths fall away, revealing the stem's smooth glossy green surface.

Taxonomy

Calamus moti was first described by Frederick Manson Bailey and published in 1896 in the journal Bulletin of the Department of Agriculture, Brisbane.Шаблон:R

Etymology

The genus name Calamus is derived from Ancient Greek κάλαμος (kálamos) and means reed or cane. The species epithet moti is the name for this plant in the language of the Djabugay people of the Barron River.Шаблон:R

Distribution and habitat

C. moti is endemic to Queensland, ranging from near Cooktown southwards to around Mackay. It grows in well developed rainforest, reaching peak development when close to water courses, and it can be found at elevations from close to sea level to about Шаблон:Cvt.Шаблон:R

Ecology and uses

The yellow lawyer cane is the host plant for the white-fringed swift Sabera fuliginosa, a butterfly of the family Hesperiidae, and the fruits are eaten by birds.

Indigenous communities of north Queensland ate the fruits and the young shoots, while the cane from the stem was used for many purposes including axe handles, fish and animal traps, shelters and baskets.Шаблон:R

Conservation

This species is listed by the Queensland Department of Environment and Science as least concern.Шаблон:R Шаблон:As of, it has not been assessed by the IUCN.
